We look at the division of 817843 by 7 
We want to divide 817843 by 7.

Let's proceed to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 7 from 8 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 7

Step 2:
The number 7 fits into 11 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 7 from 11 leaves us with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 7

Step 3:
7 goes into 47 6 times with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 42 away from 47, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 7

Step 4:
The number 7 fits into 58 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1168.0
Subtracting 56 from 58 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 7

Step 5:
If we divide 24 by 7, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 11683.0
Subtract 21 from 24 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 7

On to step 6:
33 divided by 7 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 116834.0
Deduct 28 from 33 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 116834.7
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 116834.71
Subtracting 7 from 10 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 116834.714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 116834.7142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
7 goes into 60 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 116834.71428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 116834.714285
Subtracting 35 from 40 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 116834.7142857
If we take 49 away from 50, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 116834.71428571
Subtracting 7 from 10 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 116834.71428571, with a leftover of 3e-09.
